On the 2nd we came on to the village of Khojanpur (leaving the town and cantonments of Sāgar to our left), a distance of some fourteen miles. The road for a great part of the way was over the bare back of the sandstone strata, the covering of basalt having been washed off. The hills, however, are, at this distance from the city and cantonments of Sāgar, nicely wooded; and, being constantly intersected by pretty little valleys, the country we came over was picturesque and beautiful. The soil of all these valleys is rich from the detritus of the basalt that forms or caps the hills; but it is now in a bad state of cultivation, partly from several successive seasons of great calamity, under which the people have been suffering, and partly from over-assessment; and this posture of affairs is continued by that loss of energy, industry, and character, among the farmers and cultivators, which must everywhere result from these two evils. In India, where the people have learnt so well to govern themselves, from the want of settled government, good or bad government really depends almost altogether upon good or bad settlements of the land revenue. Where the Government demand is imposed with moderation, and enforced with justice, there will the people be generally found happy and contented, and disposed to perform their duties to each other and to the state; except when they have the misfortune to suffer from drought, blight, and other calamities of season.[l2]
I have mentioned that the basalt in the Sāgar district reposes for the most part immediately upon the sandstone of the Vindhya range; and it must have been deposited on the sand, while the latter was yet at the bottom of the ocean, though this range is now, I believe, nowhere less than from fifteen hundred to two thousand feet above the level of the sea. The marks of the ripple of the sea may be observed in some places where the basalt has been recently washed off, beautifully defined, as if formed only yesterday, and there is no other substance to be seen between the two rocks.
The texture of the sandstone at the surface, where it comes in contact with the basalt, has in some places been altered by it, but in others it seems to have been as little changed as the habitations of the people who were suffocated by the ashes of Vesuvius in the city of Pompeii. I am satisfied, from long and careful examination, that the greater part of this basalt, which covers the tableland of Central and Southern India, must have been held for some time in suspension in the ocean or lake into which it was first thrown in the shape of ashes, and then gradually deposited. This alone can account for its frequent appearance of stratification, for the gentle blending of its particles with those of the sand near the surface of the latter; and, above all, for those level steps, or tables, lying one above another horizontally in parallel bars on one range, corresponding exactly with the same parallel lines one above another on a range twenty or thirty miles across the valley. Mr. Scrope's theory is, I believe, that these are all mere flowing coulées of lava, which, in their liquid state, filled hollows, but afterwards became of a harder texture, as they dried and crystallized, than the higher rocks around them; the consequence of which is that the latter has been decomposed and washed away, while the basalt has been left to form the highest elevations. My opinion is that these steps, or stairs, at one time formed the beds of the ocean, or of great lakes, and that the substance of which they are composed was, for the most part, projected into the water, and there held in suspension till gradually deposited. There are, however, amidst these steps, and beneath them, masses of more compact and crystalline basalt, that bear evident signs of having been flows of lava.[l3]
Reasoning from analogy at Jubbulpore, where some of the basaltic cappings of the hills had evidently been thrown out of craters long after this surface had been raised above the waters, and become the habitation both of vegetable and animal life, I made the first discovery of fossil remains in the Nerbudda valley. I went first to a hill within sight of my house in 1828,[14] and searched exactly between the plateau of basalt that covered it and the stratum immediately below, and there I found several small trees with roots, trunks, and branches, all entire, and beautifully petrified. They had been only recently uncovered by the washing away of a part of the basaltic plateau. I soon after found some fossil bones of animals.[15] Going over to Sāgar, in the end of 1830, and reasoning there upon the same analogy, I searched for fossil remains along the line of contact between the basalt and the surface upon which it had been deposited, and I found a grove of silicified palm- trees within a mile of the cantonments. These palm-trees had grown upon a calcareous deposit formed from springs rising out of the basaltic range of hills to the south. The commissariat officer had cut a road through this grove, and all the European officers of a large military station had been every day riding through it without observing the geological treasure; and it was some time before I could convince them that the stones which they had every day seen were really petrified palm-trees. The roots and trunks were beautifully perfect.[l6]
Notes:
1. November, 1835.
2. In the Damoh District, twenty-four miles west of Damoh. The name appears to be derived from the 'great quantity of hewn stone (Hind. patthar or pāthar) lying about in all directions'. The C. P. Gazetteer (1870) calls the place 'a considerable village'.
3. A peculiar formation, of 'widespread occurrence in the tropical and subtropical regions of the world'. It is ordinarily of a reddish ferruginous or brick-dust colour, sometimes deepened into dark red. Apparently the special character which distinguishes laterite from other forms of red-coloured weathering is the presence of hydrous oxide of alumina in varying proportions. . . . 'Though there is still a great deal of uncertainty about the way in which laterite was formed, the facts which are known of its distribution seem to show that it is a distinct form of weathering, which is confined to low latitudes and humid climates; its formation seems to have been a slow process, only possible on flat or nearly flat surfaces, where surface rain-wash could not act' (Oldham, in The Oxford Survey of the British Empire, vol. ii, Asia, p. 10: Oxford, 1914). It hardens and darkens by exposure to air, and is occasionally used as a building stone.
4. The Sāgar mint was erected in 1820 by Captain Presgrave, the assay master, and used to employ four hundred men, but, after about ten or twelve years, the business was transferred to Calcutta, and the buildings converted to other uses (C. P. Gazetteer, 1870). Mints are now kept up at Calcutta and Bombay only. The Biās is a small stream flowing into the Sunār river, and belonging to the Jumna river system. The name is printed Beeose in the original edition.
5. Since the author's time the conditions have been completely changed by the introduction of railways. The East Indian, Great Indian Peninsular, and other railways now enter the Nerbudda Valley, so that the produce of most districts can be readily transported to distant markets. A large enhancement of the land revenue has been obtained by revisions of the settlement.
